[go-nuts] some questions to use ScalarMult

I am using ECC ScalarMult to get a point. When I use the amd64 accelerated version, the result is wrong; by using the generic version, the result is normal. My code is here: k, _ := hex.DecodeString("646d22e7aee42d44bd15cdf58006359283e1da83c2670b25d44906d03e9ed4eb") X, _ :=

Re: [go-nuts] Windows - syscall.GetProcessTimes() always shows 0 values.

Steven, your example is really helpful! I didn't know Windows had a lower time interval for internal timers, so that's good to know, thanks for getting me unstuck! Thought I was losing my mind. Is there a reason to pass the PID around instead of using the pseudo handle? I'm new to the core

Re: [go-nuts] Windows - syscall.GetProcessTimes() always shows 0 values.

Your main problem is the fact that the Windows time interval is 16ms by default. It uses this value for its internal timers and thread time quantum, which effectively means you won't see any changes until they have added up to a min of 16ms. You can see this by changing the 16ms in the following

Yes those I also use in init sometimes but then you are in control of your templates and regexes and things usually blow up quickly during development which makes you fix it promptly. It is not quite the same though as I understood Peters question to be. The analogy would be the html/template to

Re: [go-nuts] Re: How to parallelize text/template long running functions?

Ah! I think I have the kernel of a usable idea here. Thanks. How does this sound: template 1 outputs template 2. Input to template 1 kicks off the goroutines and places {{ get_results token_xyz }} as the output, but also has an output channel that we can wait on for all of the answers Then,

Re: [go-nuts] To panic or not to panic, that's the question

Init seems very harsh, how can you ensure proper configuration then? Otherwise I don't mind oanics during object creation or explicit initialization. Panics in mid execution less so but parhaps there are cases where it is warranted. ons 31 maj 2017 kl 21:25 skrev Peter Kleiweg

[go-nuts] To panic or not to panic, that's the question

If a package can't be used because some precondition can't be fulfilled, you can use a panic. Then the whole program will crash at start-up. The alternative would be to not panic in the init, but have all function calls return an error. If the package is used in a large program, part of it may

Re: [go-nuts] Re: Using Context to store TraceIDs

In Erlang, we have a similar concept to the Context bag called the Process Dictionary. Its use is generally a nono because it breaks the rules for functional programming and allows you to have a shared space. We like to pass every argument explicitly in order to make it easier to read the code.

Re: [go-nuts] Re: How to parallelize text/template long running functions?

This is almost certainly going to be a case where you have the correct solution and I don't have the go experience to properly understand it. I wasn't quite understanding how your code was "patching" the results and how the template package knows to wait for it. Let me describe my problem. I

[go-nuts] Re: Using Context to store TraceIDs

Hi Bill, Generally if you have a Trace ID, you are also doing something that involves multiple systems, processes, or routines. If that is the case, you also need a way to cancel your resource. Thus Trace ID is included with values in the context and not separated. When Dave voiced his own

Both of my described approaches run the funcs serially however it does not wait for the response and later patxhes the results. Can you describe the whole thing you are building? Piecing the requirements and purpose together from comments is difficult. I.e. how much memory, how big is request

[go-nuts] Re: How to parallelize text/template long running functions?

The best thing I can think of is to modify text/template to add futures support, and then do multi-pass rendering. The place to add this looks relatively simple, however the implementation looks complicated (and I just wrote my first program in go a couple weeks ago...) The problem that I see

Re: [go-nuts] How to parallelize text/template long running functions?

This is basically the answer that everybody gives, however this is just not an option. (Which also makes this a very frustrating question to ask, as many people insist that you are just simply wrong for asking it without any understanding of our requirements.) We have data sets that we cannot

Hi, we see a clear correlation between GC and latency spike in our Go server. The server uses fairly large amount of memory (20G) and does mostly CPU work. The server runs on a beefy box with 32 cores and the load is pretty light (average CPU 20-30%). GC kicks in once every 10-20 seconds and

[go-nuts] How to parallelize text/template long running functions?

I am designing a system that will heavily use text/template processing and I've run into one issue that is going to be a show stopper for me if I can't figure out a way around it. Execute() on a template will run all of the functions in the template serially. For example, when you run the

[go-nuts] Re: did anyone tried // template exec ?

My problem is that I have a very large data set that is very expensive (memory/compute) to get, and only the template knows which data it needs to use. Computing the data in go before template processing would waste a whole lot of time/memory that I dont have. On Tuesday, May 30, 2017 at
